Abstract
Though strongly linked to landslides, hydropedological characteristics are inadequately investigated in
Manafwa catchment. This study investigated hydropedological characteristics at medium landslide sites
in Manafwa catchment. The design included 12 infiltration experiments that were conducted at each site.
To determine the selected soil physical properties, composite soil samples were extracted from the
infiltration sites for soil laboratory analysis. Soil cores were extracted to determine saturated hydraulic
conductivity (Ksat) and bulk density. The observed high infiltration rates and rapid Ksat underscore the
susceptibility of the studied sites to landslide hazards. Additionally, soil organic matter, clay content, and
bulk density further contribute to the understanding of the hydropedological factors influencing land
slide occurrences. These findings reveal the need for comprehensive investigations into hydropedologi
cal characteristics of other landslide categories to assist in landslide risk assessment and management strategies
